This invention relates to the waterproofing of walls to the end that water due to capillary action, will be prevented from getting beyond the outer face of a wall, and the invention consists in an improved method for waterproofing the walls as well as in the provision of an improved fabric for use in the Waterproofing of the walls.

Among the objects of the invention are, to fulfill a need of waterproofing buildings that have troubled architects and engineers for many years; to provide a method for waterproofing walls which will be more economical and more effective than the methods now generally em- 5 ployed; to obviate the applying of waterproofing on the outside surfaces of buildings built with brick or stone that absorbs water through the brick and mortar joints; and to eliminate application of waterproofing in the form of asphalt or tar base on the inside surfaces of walls.

The invention together with its objects and advantages will be best understood from a study of the following descriptiontaken in connection with the accompanying drawings.

In the drawings:

Figure 1 is a fragmentary sectional View through a wall structure illustrating the invention.

Figure 2 is a plan view of one face of a sheet of waterproofing fabric embodying the features of the present invention.

Figure 3 is a similar view of an opposite face of the waterproofing sheet.

Figure 4 is a plan view with a corner portion of one of the layers rolled back to show the asphalt filling.

Figure 5 is a sectional view through the sheet. Referring to the drawings by reference numerals it will be seen that 5 indicates generally a sheet lining which in accordance with the present invention is interposed between the outermost layer 6 of face brick and the innermost layer l of brick which layer also includes the usual backup tile 8. As will be noted, portions of the sheet extend across the back of the sill 8 as well as between the sill and the next adjacent back-up tile 8. It will also be noted that the sheet 5 is also trained around the inner ends of the heading or binding courses of brick l0. Where anchors II are used, for example, for anchoring stone, terra cotta or brick facing to-the brick back up wall, I provide at the inner side of the sheet 5 a substantially channel-shaped shield l3 which is apertured to accommodate the anchor II as shown in Figure 1. This shield II is filled with cement or other suitable cementitious material I4. Such a shield with its plastic waterproofing material I4 will take care of the puncturing of the sheet 5 caused by the passage of the anchors ll, therethrough and will insure perfect 5 tightness.

The sheet 5 may be made up of a plurality of sections and in Figures 2 to 5 inclusive I have shown a preferred construction of sheet section 5. The sheet or section in the embodiment illus- 1g trated consists of facing sheets I5 and I6 respectively. Between these sheets and adhesively uniting these sheets i5 and I6 together is a layer of asphalt ll. In the present instance, the sheet i5 is in the form of thin copper or aluminum sheet- 15 ing which in addition to being a waterproofing also acts as an insulator, while the sheet I6 is of paper or a suitable paper product.

While a sheet of waterproofing material embodying the features above enumerated, and es- 20 pecially the facing sheet i5 of thin copper sheeting will be found, in actual practice, to be most effective, desirable results can be also obtained from a waterproofing sheet wherein both face sheets are of paper instead of, as in the embodir ment illustrated, one facing sheet being of paper while the other sheet is of thin copper sheeting.

Any waterproof sheet consisting of facing sheets with a layer of asphalt therebetween will be found to be impervious to water and consequently when arranged between the different courses of brick and about the heading or binding courses in a manner taught by the present invention and shown in Figure 1, will be found admirably adaptable to the preventing of water 35 working back beyond the face brick 6 of the wall and thus serve the purpose of acting as a nonconductor to the end that the dryness of the inner part of the wall u'nlder practically all reasonable conditions will be insured. 40

Having thus described the invention, what is claimed as new is: i

l. A waterproof wall comprising an inner wall structure of brick, an outer wall structure of facing brick, waterproof multiple sheet material in- 45 terposed between the inner and .outer walls, an apertured channel-shaped shield disposed at the side of the sheet material opposite to the outer wall of facing brick with the open side of the channel of the shield disposed against the sheet 5 material, anchoring elements extending through the sheet material and said shield and respectively having their respective opposite ends imbedded in the inner and outer wall structures, and a. filling of cementitous materi l within the 5 having their respective opposite ends anchored within said inner and outer layers of brick, and means imbedded within the inner layer of brick adjacent the anchor-punctured area of said sheet material for sealing the punctured area of said 5 sheet material.
